Step-by-step explanation:

Answer:

1) 12 boxes

2) 3, 6, 12

3) 12

4) 110 degrees

Step-by-step explanation:

1) Count the rectangles. Multiply the length of the rectangle in boxes to the width of rectangle in boxes.

Length: 4 boxes

Width: 3 boxes

4 x 3 = 12

12 boxes

2)

10% of 30 is 0.1 times 30.

0.1 x 30 = 30/10 = 3

20% of 30 is 0.2 times 20.

0.2 x 30 = 30/5 = 6

40% of 30 is 0.4 times 20.

0.4 x 30 = 30/2.5 = 12

3) Count the cubes. Reminder there are 2 boxes you cannot see.

The population of the United States would increase by approximately 2,628,000 people in 1 year at the given rate.

To determine how much the population of the United States would increase in 1 year at the given rate, we need to convert the time from seconds to years.

There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. So, the number of seconds in a day is:

60 seconds/minute * 60 minutes/hour * 24 hours/day = 86,400 seconds/day.

Next, we calculate the number of days in a year. In general, a non-leap year has 365 days. Therefore, the number of seconds in a year is:

86,400 seconds/day * 365 days/year = 31,536,000 seconds/year.

Now, we can calculate the population increase in 1 year. The rate of increase is 1 person every 12 seconds. So, the population increase in 1 year is:

31,536,000 seconds/year / 12 seconds/person = 2,628,000 people.

Therefore, the population of the United States would increase by approximately 2,628,000 people in 1 year at the given rate.

Using a linear equation, the formula for the sum registered is:

\(C(n) = 5n + 175\)

----------------------------

A linear equation has the following format:

\(y = mx + b\)

In which:

In this problem:

\(m = \frac{975 - 775}{160 - 120} = \frac{200}{40} = 5\)

Then

\(C(n) = 5n + b\)

(120,775) means that when \(n = 120, C(n) = 775\). We use this to find b.

\(C(n) = 5n + b\)

\(775 = 5(120) + b\)

\(b = 775 - 600\)

\(b = 175\)

Thus

\(C(n) = 5n + 175\)

the probability that a random sample of size 4 will have a mean between 110 and 130 is approximately: 0.0062 or 0.62%.

To find the probability that a random sample of size 4 from a population with a mean of 100 and a standard deviation of 16 will have a mean between 110 and 130, we can use the Central Limit Theorem.

According to the Central Limit Theorem, for a random sample of size n taken from a population with any distribution, as long as the sample size is sufficiently large, the distribution of sample means will approach a normal distribution regardless of the shape of the population distribution.

In this case, the sample size of 4 may not be considered large, but we can still approximate the distribution of sample means as approximately normal due to the Central Limit Theorem.

To calculate the probability, we need to convert the given values to z-scores using the formula:

z = (x - μ) / (σ / √n)

where x is the desired sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

For a sample mean of 110:

z₁ = (110 - 100) / (16 / √4) = 2.5

For a sample mean of 130:

z₂ = (130 - 100) / (16 / √4) = 7.5

Next, we can use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores.

P(110 ≤ X ≤ 130) = P(2.5 ≤ Z ≤ 7.5)

Using a standard normal distribution table, the probability corresponding to a z-score of 2.5 is approximately 0.9938, and the probability corresponding to a z-score of 7.5 is approximately 1.

Therefore, the probability that a random sample of size 4 will have a mean between 110 and 130 is approximately:

P(110 ≤ X ≤ 130) = P(2.5 ≤ Z ≤ 7.5) ≈ 1 - 0.9938 = 0.0062 or 0.62%.

The value of "a" is approximately 1.83 given that the absolute value of the difference of the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive.

We are given that the absolute value of the difference between the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive. We need to find the value of "a".

Let the two roots of the equation be r1 and r2, where r1 is not equal to r2. Then, we have:

|r1 - r2| = √(61) / 3

The sum of the roots of the quadratic equation is given by r1 + r2 = -5 / a, and the product of the roots is given by r1 × r2 = -3 / a.

We can express the difference between the roots in terms of the sum and product of the roots as follows:

r1 - r2 = √((r1 + r2)² - 4r1r2)

Substituting the expressions we obtained earlier, we have:

r1 - r2 = √(((-5 / a)²) + (4 × (3 / a)))

Simplifying, we get:

r1 - r2 = √((25 / a²) + (12 / a))

Taking the absolute value of both sides, we get:

|r1 - r2| = √((25 / a²) + (12 / a))

Comparing this with the given expression |r1 - r2| = √(61) / 3, we get:

√((25 / a²) + (12 / a)) = √(61) / 3

Squaring both sides and simplifying, we get:

25 / a² + 12 / a - 61 / 9 = 0

Multiplying both sides by 9a², we get:

225 + 108a - 61a² = 0

Solving this quadratic equation for "a", we get:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61)

Since "a" must be positive, we take the positive root:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61) ≈ 1.83

Therefore, the value of "a" is approximately 1.83.

Answer:400

Step-by-step explanation

in order to find slope you put the change in y over the change in x, y gains 1200 units while x gains 3 units, this means we get 1200/3 and we can simplify it to 400

Answer:

400

Step-by-step explanation:

We can use the formula \(\frac{rise}{run}\) to find slope!

So first we find points on the graph. The first point we see is 600. The second point we see is 1,400. Next, we find the rising distance between 1,400 and 600 which is 800. Now we look at the running distance which is 2. Now we plug it into the \(\frac{rise}{run}\) formula.

The formula should now look like this:

\(\frac{rise}{run}\\\) = \(\frac{800}{2}\)

\(\frac{800}{2}\) = 400

So the slope is 400

The lowest score that Liliana can earn on the fourth and final test of the term if she wants to have an average of at least 83 is of 80.

The mean of a data-set is obtained by the sum of the numeric values of all observations in the data-set divided by the number of observations, which is also called the cardinality of the data-set.

In this problem, the numeric values of the four observations are given as follows:

86, 88, 78, x.

In which x is her grade on the last test.

Then the mean is calculated by the rule presented as follows:

M = (86 + 88 + 78 + x)/4 = (252 + x)/4.

She wants an average of at least 83, hence the minimum grade x of the final test is calculated as follows:

83 = (252 + x)/4

252 + x = 83 x 4

x = 83 x 4 - 252
